Investment Objective/Strategy -The First Trust North American Energy Infrastructure Fund is an actively managed exchange-traded fund. The Fund's investment objective is to seek total return. The Fund's investment strategy will have an emphasis on current distributions and dividends paid to shareholders. Under normal market conditions, the fund will invest at least 80% of its net assets in equity securities of companies headquartered or incorporated in the United States and Canada engaged in the energy infrastructure sector. The Fund will invest primarily in publicly-traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates, pipeline companies, utilities, and other companies that derive at least 50% of their revenues from operating or providing services in support of infrastructure assets such as pipelines, power transmission and petroleum and natural gas storage in the petroleum, natural gas and power generation industries.

There can be no assurance that the Fund's investment objectives will be achieved.

The price used to calculate market return is determined by using the midpoint between the highest bid and the lowest offer on the stock exchange, on which shares of the Fund are listed for trading, as of the time that the Fund's NAV is calculated.

Standard Deviation is a measure of price variability (risk). Alpha is an indication of how much an investment outperforms or underperforms
on a risk-adjusted basis relative to its benchmark.Beta is a measure of price variability relative to the market. Sharpe Ratio is a measure
of excess reward per unit of volatility. Correlation is a measure of the similarity of performance.

*Performance data quoted represents past performance. Past performance is not a guarantee of future
results and current performance may be higher or lower than performance quoted. Investment returns
and principal value will fluctuate and shares when sold or redeemed, may be worth more or less than
their original cost.

After Tax Held returns represent return after taxes on distributions. Assumes shares have not been sold.
After Tax Sold returns represent the return after taxes on distributions and the sale of fund shares. Returns
do not represent the returns you would receive if you traded shares at other times. Market Price returns are
based on the midpoint of the bid/ask spread on the stock exchange on which shares of the fund are listed for
trading as of the time that the fund’s NAV is calculated. Returns are average annualized total returns, except
those for periods of less than one year, which are cumulative.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and
do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax
situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold
their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

Indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the performance shown. Indexes are unmanaged and an investor cannot invest directly in an index.

The expense ratio for this fund is 0.95%.

S&P 500 Index - The Index is an unmanaged index of 500 stocks used to measure large-cap U.S. stock market performance.

Blended Benchmark - The Blended Benchmark consists of the following two indexes: 50% of the Philadelphia Stock Exchange Utility Index which is a market capitalization-weighted index composed of geographically diverse public U.S. utility stocks; and 50% of the Alerian MLP Total Return Index which is a float-adjusted, capitalization-weighted composite of the 50 most prominent energy Master Limited Partnerships (MLPs).

Fund shares are purchased and sold on an exchange at their share price rather than net asset value (NAV), which may cause the shares to trade at a price greater than NAV (premium) or less than NAV (discount).

The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.

ETF Characteristics

The fund lists and principally trades its shares on the NYSE Arca, Inc.

Investors buying or selling fund shares on the secondary market may incur customary brokerage commissions.
Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net
asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be
redeemed directly from the fund by authorized participants, in very large creation/redemption units. If the fund's authorized participants are unable
to proceed with creation/redemption orders and no other authorized participant is able to step forward to create or redeem, fund shares may trade at
a discount to the fund's net asset value and possibly face delisting.

Risk Considerations

The fund's shares will change in value, and you could lose money by investing in the fund. One of the principal risks of investing in the fund is market risk. Market risk is the risk that a particular stock owned by the fund, fund shares or stocks in general may fall in value. The fund is subject to management risk because it is an actively managed portfolio.
In managing the fund's investment portfolio, the sub-advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no assurance that the fund's investment objective will be achieved.

The fund may invest in small capitalization and mid capitalization companies. Such companies may experience greater price volatility than larger, more established companies. The fund may use derivatives which can lead to losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivatives.

The fund invests primarily in securities of companies headquartered or incorporated in the U.S. and Canada. Accordingly, an investment in the fund may be more volatile than an investment diversified across several geographic regions. An investment in a fund containing securities of non-U.S. issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers. The fund may invest in depositary receipts which may be less liquid than the underlying shares in their primary trading market.

The fund is concentrated in securities of companies in the energy sector which involves additional risks, including limited diversification. The companies engaged in the energy sector, which includes MLPs and utilities companies, are subject to certain risks, including price and supply fluctuations caused by international politics, energy conservation, taxes, price controls, and other regulatory policies of various governments.

Energy infrastructure companies may be directly affected by energy commodity prices, especially those companies which own the underlying energy commodity. A decrease in the production or availability of commodities or a decrease in the volume of such commodities available for transportation, processing, storage or distribution may adversely impact the financial performance of energy infrastructure companies.

An investment in MLP units involves risks which differ from an investment in common stock of a corporation. Holders of MLP units have limited control and voting rights. In addition, there is the risk that a MLP could be taxed as a corporation, resulting in decreased returns from such MLP. Rising interest rates could adversely impact the financial performance of MLPs, MLP-related entities and energy companies. The fund may be subject to additional risks pertaining to currency, interest rates and derivatives.

Changes in currency exchange rates and the relative value of non-US currencies may affect the value of a fund's investments and the value of a fund's shares.

The fund is classified as "non-diversified" and may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers.
